2-3n=n+10
so two less than three is subtracting two minus three. than three times a number; we dont know that number so we put it as a variable. in this case n. so they are multiplying right now. "is" means equals. than the same number, which is n, plus 10. so add ten with n.
It would end up being 4/5 if you brought it to the lowest tern.
The Third Angle Theorem states if two angles are congruent to two angles in another triangle, the third angles are congruent too. Because a triangle has <span><span><span>180 degrees </span></span></span>the third angle in any triangle is <span><span><span>180 degrees </span></span></span>minus the other two angle measures
<span>m angle 2 = a°, m angle 3 = b°, m angle 4 =
m<4 = m<2 + m<3
m<4 = </span>a + b
answer
<span>a + b</span>
